I bought these for my ex-husband's business. He wanted to put flyers of his product on doors therefore thought it would be easier to hole punch the flyers and loop the rubber bands in order to hand them on doors. Worked perfectly without a big fuss or mess and people were less apt to throw them away which meant they were actually looking at the product. It was a great investment for less than $4 and still have a some left for the next batch that need to hung. In addition it's an easy project to involve the kids and not have to worry about dangers.
I love these. They are the perfect size. I am a tax preparer and are some times presented with piles of paperwork. These will keep my customers folders and documents securely together.
